hi dk'
not sure who really needs the booster, obviously LONGER rigs may.
i purchased the battery powered booster but didn't use it for the first week...
((stuff is returnable))
with a 34 and LONG f250 in REALLY REALLY COLD weather (8-15 degrees)...
the system occasionally 'lost' a tire or 2.
put a battery IN the booster and placed it INSIDE the stream front overhead locker...
and totally solved the lost signal issue.
(IF one were to get the WIRED booster,
it would be easy to install and mount INSIDE the lp tank cover.)
in warmer weather the signal may not have been weak but i kept the booster.
the display has a rechargeable battery
and AFTER 2-3 charges it seems to last 3-5 weeks in daily use.
as i recall the valve stem HEADS are a TINY bit lighter than the other major system too.
ken, hiho and i seem to be satisfied with this gear.

the round
12v charger plug thing, FELL APART 2 weeks ago,
i emailed them and they sent me a new charger under warranty
(later went to radio shack and found generic chargers that are compatible)
cheers
